Django RestApi server Overview

Goal

Our Django Server can work with MySQL Database and provides APIs:

• GET /customers/: get all customers
• GET /customers/[id]: get a customer by id
• GET /customers/age/[age]: find all customers by age
• POST /customers/: save a customer
• PUT /customers/[id]: update a customer by id
• DELETE /customers/[id]: delete a customer by id
• DELETE /customers/: delete all customers

Architecture

Project structure

There are several folders and files in our Django project:

• customers/apps.py: declares CustomersConfig class (subclass of the django.apps.AppConfig) that represents our Django app and its configuration.
• gkzRestApi/settings.py: configures settings for the Django project, including INSTALLED_APPS list with Django REST framework and Customers Application.
• customers/models.py: defines Customer data model class (subclass of the django.db.models.Model).
• migrations/0001_initial.py: is generated by makemigrations command, includes the code to create the Customer model, will be run by migrate to generate MySQL database table for Customer model.
• customers/serializers.py: declares CustomerSerializer class (subclass of rest_framework.serializers.ModelSerializer) for Customer instances to manage serialization to JSON and deserialization from JSON.
• customers/views.py: contains methods to process HTTP requests and produce HTTP responses (using CustomerSerializer).
• customers/urls.py: defines urlpatterns to be matched with request functions in the views.py.
• gkzRestApi/urls.py: defines root URL configurations that includes the URL patterns declared in customers/urls.py.
